I have a 2006 Jeep Liberty CRD that I purchased a couple years ago. Recently, I have the injectors replaced and my fuel economy changed.

I am not sure if the prior ecu had a tune done on it, but I am wondering now that the fuel is less economical that re-calibrating for the new injectors would have changed the programming. Maybe the prior owner had it tuned, and the new injectors reflashed the ecu back to factory.

The Jeep VIN is: 1J4GL58576W154126-

I am not sure if you can tell if this was a Green Diesel tune, please let me know.
